Going to Sibastro

September 11th, 2010 by Ivan Boldyrev

I finally paid for one-night participation on SibAstro (17-18 of September).

Perhaps, I would spend there full two nights, but I have to go Barnaul (capital of nearby region) for 5 days soon after SibAstro.

ObservationManager 1.020 in gentoo-astronomy overlay

September 10th, 2010 by Ivan Boldyrev

I have managed to create ebuild for Observation Manager 1.020 recently released. Old versions were not working with system install (AFAIR, they attempted to write to /usr/share/), but 1.020 seems to work.

It was a difficult task, as package has two source packages with individual Ant project for modules in each package.

If you are Gentoo-using amateur astronomer, fill free to check my Gentoo Astronomy overlay!

Nice map. More maps.

Too pity there are no total solar eclipses in Novosibirsk anymore 🙂

Gentoo Linux Astronomy overlay

March 11th, 2010 by Ivan Boldyrev

I have started an Astronomy overlay for Gentoo Linux (i.e. repository for astronomical software that can be installed on Gentoo Linux).

The following packages are currently packaged:

  • SkyChart (aka Cartes du Ciel)
  • VirtualMoon
  • JSatTrak
  • IridiumFlares

Note that JSatTrak depends on some packages from java-overlay.

New variant of starchartjs

February 11th, 2010 by Ivan Boldyrev

I have created another variant of starchartjs that uses HTML5 Canvas element with normal browsers and excanvas (VML emulation of Canvas) with Internet Explorer:

New version uses Rey’s constellation figures with more stars and lines (it was driving force for Canvas migration, as Canvas is faster).

It also draws planets (I could add it to old SVG/VML version too).

Please, test with various browsers and platforms.

P.S. Here are competitors:!!!

Updated at Jan 2012: StarchartJS is now open-source, you may see better demo at

starchartjs: new astonomical web toy

February 4th, 2010 by Ivan Boldyrev

This page displays real-time star chart for my location (it could for any other). The chart is updated each 2 minutes.

The map is created with RaphaelJs library, constellation figures are stolen from Stellarium.

I plan to use it as a component for my future projects.
